Product information

Description

Kathrein VOS 138/RA 2.0 is a compact TV signal amplifier designed to improve terrestrial and cable television reception in homes and small buildings. It accepts AC power at 50/60 Hz and provides stable amplification to reduce noise and level variations, helping to deliver clearer picture and sound without changing distribution wiring.

The amplifier stabilizes varying signal levels from outdoor antennas or cable feeds, improving overall reception quality and minimizing pixelation and audio dropouts.

Suitable for

  • Domestic TV reception improvement in apartments and houses
  • Small commercial spaces such as offices or waiting rooms
  • Systems where a compact, wall- or rack-mounted amplifier is required
  • Environments with fluctuating terrestrial or cable signal strength

Key specifications

  • Housing dimensions: 218 × 80 × 150 mm
  • Weight: 1.25 kg

How to use

Install the Kathrein VOS 138/RA 2.0 amplifier between the antenna or cable feed and the receiver or distribution network, following local safety regulations for mains-powered equipment. Connect the input coaxial from the antenna or incoming cable to the amplifier input, then connect the output to your TV set or distribution amplifier. Supply AC mains power at the rated frequency (50/60 Hz) and check signal levels on your receiver; adjust any available gain controls according to the receiver manufacturer's guidance to avoid overload. Ensure all coaxial connectors are properly tightened and weatherproofed if installed outdoors.

Usage recommendations
